To all whom 'z'mai/ concern:

Beit known that I, BENJAMIN UBL, of Anderson, county ofv Madison, andState of Indiana, have invented a 4certain useful VVeighing-Scale; and Ido hereby de:

clare that the following is a full, clear, and

exact description thereof, reference.A being- `had to the accompanyingdrawings.

The object of this invention is to cheapen, simplify' and improafe theoperationv tof weighing scales; particularly of the computing type.

The'chief feature of the invention con- .operation 'with the' loadreceiving member and the load, andconnectionbetweenl an in'- di'cat-orand the weighing beam whereby the beam controls the vmovement 'of theindicator to indicate the effect :of a'n applied' load.

i In the drawings-Figure lisacent-ial ver-.J -ticalsectionlongitudinally of the scale withA parts brokenA away. Fig1l`2is'a' section lon the line 2-2 .of Fig. 1,' but on alargarV scale,showing, however, 'only the springs.

and their mounting.l Figf3 is a section somewhat similar .to thatinlEig. 1,.fshow-f ing the' pos1tion of the parts with a four pound load.Fig. 4 -is a section'on the\ line 4 4 of Fig.

There is shown nary-type with a lower housingll and an lupper housing12'. A scalebeam 13 is fulcrumed at 14 between its ends. -A loadre-v.ceiving member l5 -is-.carri'ed byV saidvframe. outside ortov one sideof the fulcrumbyna- .braclzct 16.*' The other end of'the'beaml13projects into the housing and'operats ver tically through a slot "17.fv'Ihereis also a tare beam'lS secured to said scale o'r weighing vbeam13 and the tare beam'has poisesr 19 thereon. The inner en'd of theweighing beam 13 is'connectedwith a'dash pot 20 for-l checking thevibration thereof.v There is also an L-shapeA bar'21 projecting throughtheslot' 17 of the housing with its inner'end I extending upwardly inthe housing and and `connected with the bracket 16 which* pivot-ed tothe free end 'of t-he arm 22 which is pivoted' at 23 Sto the upperhouslng 12.

An outer portion of said bar 21 is horizontal carries the loadreceiving. member. This check is to maintain the load receiving mei'nberin a horizontal position.

D. EiuAN-v herein, a base 10 of ford'i;

In the upperlliousin 12 there is a chart 25 graduated .to vweigl tandvalue indica-l 26 osoillates and moves across the chart asa| loadisapplied and ,it has 'on it price-perpound indications which registerwith the lions, but either. class of those graduations` l i may beomitted, as desired. Anindicator" totalfvalueindications onrthe chart.-Said' I lindicator is mounte'd oscillatory on a rod 2 7'.A secured tothehousing and'is provided with .an oppositely extending counterweight28. The function of the coun-terweight is merely to cunterbalance theindicator 26 and not'A to actuate it.

The foregoing parts of the construction are old and are shown herein'merely to illustrate the invention, although some uof them may, bemodified, as do not wish to limit "the invention to any particular oon-,.struction of weighing scales. .f A 11 'and base 10 a ,'verticalfbar 30is secured and it" has inwardly extending upper and lower ,arms 31'through which .set screws 32 project toward To the lower' housing eachlotherljfA springholding'frame is mounted in connectionwith said bar. 30so. yas to be vertically adjusted thereon. It conysists 'of a :verticalbar 33 having slots 34 through which headed screws 35 project .thatscrew into the b ar 30. The set screws 32 'vertically adjust'and holdthe wire hold- .ing frame in position'. This frame includes the bar 33an'd the upper and lower .arms 36 parallel with each other. A lowerspring 37 vis's'ecured tothe lower arm 36 and an.

upper lspring 38 is secured to the upper arm These arespiral springs-andoppose each 'other 'with adjacent ends lsecured to a lren'novable 'rod.4 0 extending through and between gthe. divided or yokd arms of th'ebeam 13, as shown in Fig. 2. One of the A'springs isrconnected ivith'itsarm by-a screw V42 with' a nut 43 thereon so that the tension.

oi bothjspringscan be modiiied.

A rod' 143'- ispivoted at its lower end to the beam 1'3 and carries onits upper end'a "rack bar44'thatl is'held against a gear 45 by A springswhic p i or exerting some pullon the -beam 13; Thev 50' is secured tothe rod 43 or ,some other beam or its connece 'beam while sealingsprings are so arranged and adjusted that when there is no load theirpulls on the beam are equal. When load is applied and the inner endo-the beam 13 moves upwardly,

the pull ofthe lower spring 37 will increase while the pull of the upperspring 38 will correspondingly diminish. Hence, the combined 'ture willrnot affect wtlresemnbined action of thesprings 411t o11ftre leven/ftwill aii'ect both springs-:si1nilarly,.but since their iniuenees`ane/oppostm the temperature4 changes y1nthe one springwill offset theAtemperature changes in the other spring.-`

I claim as my iventionz. 1. A weighing scale including a base, a

'housing on one part of the base, a beam ful# crumed between its ends onthe base outside of the housing and with one end weighted and normallyover-balanced and projecting into tie housii'g, a load receiving membercarrie, by .the outer end of said beam, a pair connection with thelinner end of said lever so as to actoppositely and 'equally on said.beam when there is no load, an indicator ffulcrumed in'the housing, aconnection between theinner end ofthe beam andthe indicator foractuating thelatter, and a weight counterbalancing the indicator,substantially *as set forth.

f2. A weighing scale including a base, a housing extending upwardlytherefrom, a *Weighing beam ulcrumed between its lends Af/"on said baseoutside the housing and with one end projecting into the housing, a loadaction of the springs' will vary with the' variations in the load.The-work 'of'st't'uab' .ing the indicator, since it is balanced, willvalways be the sanie, Changes 1n temperareceiving 'member carried bytheouter end of said beam, a vertically adjustable spring supportlmounted in connection with the housing with one arm' above and ,anotherarm belo'w said beam, spiral ,springs of subi stantially equalcharacter' coniiected with said beam and with the arms of said springsupport, one spring above 'and one below the beam, and means actuated bythe inner end of the beam for'indicating theei'ect of an j applied load.

L In witness whereof, I have .hereunto afiiXed my signature in thepresence of the witnesses herein named.
